For the first time, researchers at the University of California, Davis, have demonstrated that forest trees have the ability to tap into nitrogen found in rocks, boosting the trees' growth and their ability to pull more carbon ...

Human nitrogen additions to the soil may reinforce the greenhouse effect. Nitrogen additions tend to boost plant growth, so that terrestrial ecosystems absorb more carbon dioxide from the atmosphere. But recent studies ...

During the 1970s and 1980s, researchers and policymakers became increasingly worried about multiple consequences of acidic emissions of sulfur dioxide and nitrogen oxides from the stacks of power stations, and eventually ...

NASA's Aura Satellite has provided a view of nitrogen dioxide levels coming from the fires in New Mexico and Arizona. Detecting nitrogen dioxide is important because it reacts with sunlight to create low-level ozone or smog ...

Yellow starthistle already causes millions of dollars in damage to pastures in western states each year, and as climate changes, land managers can expect the problem with that weed and others to escalate.

(PhysOrg.com) -- A solar-powered sensor station to monitor in real time the concentration of gases that are key culprits in climate change and air pollution has been installed on a QUT Gardens Point roof as part of an international ...

One helpful action anyone can take in response to global warming is to plant trees and preserve forests. Trees and plants capture carbon dioxide during photosynthesis, thereby removing the most abundant greenhouse gas from ...

Programs that allow facilities to buy and sell emission allowances have been popular and effective since they were introduced in the U.S. two decades ago. But critics worry the approach can create heavily polluted "hot spots" ...

(PhysOrg.com) -- This composite of three artists' renderings from 1975 was only wish fulfillment for an unnamed JPL artist; however, the landscape and the rendered shapes took into account what was known about Mars that year.
